I have taken my car to the Honda dealership on multiple occasions because my car has stopped accelerating while driving on the interstate. The car will flash the check engine light and completely stop accelerating while driving. I was first told it was the fuel pump that was recalled and waiting over a year on the recalled part and multiple times breaking down while driving they finally replaced the part. After the dealership replaced fuel pump I continued to have problems unfortunately happening more often and worse than before replacing the fuel pump. I was then told my car was misfiring and needing a tune up which would involve replacing all four coil packs and spark plugs. I replaced all of these recommended parts with no resolution to my problem. I have since be told by the dealership my car needs all four fuel injectors replaced after running the diagnostic tests. After doing research it seems to be a common problem with this make and model car. I can-??t believe with as many cars with this same issue and the safety issues with completely stalling in the middle of traffic there are no recalls on these cars.

I feel like my car should be under recall it-??s so many other who experiencing the same thing. all of my lights are on, on the dash. Check engine light down to my cruise control not working. as I drive it-??s stalling and jerking. I went to the dealership to have my spark plugs and my fuel injectors replace and it started back doing the same thing. Spent thousands just to be going through the same exact thing.

My family's 2019 Honda Accord with ~80k miles suddenly had all the warnings lights flashing on the dashboard in early July 2025. The initial diagnostic reader showed a Cylinder 3 misfire. After replacing spark plugs, the warning lights returned after one week; at that time, the ignition coil was replaced but the warning lights returned again after one week of driving. The Honda dealership performed further diagnostics and tests, ultimately reporting that the engine needed fuel injectors replaced AND a head gasket. It is important to mention that when we initially called the dealership's service department to make an appointment, the Service representative that answered the phone immediately recognized this issue, saying that it is a well known issue with Accord 1.5 turbo engines. Honda Corporate has stated that the car is outside of the manufacturer's warranty and that there is no recall. Note that there are class action lawsuits in the US on this matter, as well as lots of online traffic of car owners experiencing this issue with the Honda 1.5T engine. It appears that there is a serious design flaw in the engine.

While driving my 2019 Honda Accord, the engine began misfiring and losing power. A diagnostic scan showed misfire codes (P0300-?"P030X). The issue was traced to coolant leaking into the combustion cylinder due to a head gasket defect. This caused engine hesitation, reduced acceleration, and risk of stalling while in traffic. I have learned that Honda has issued a Technical Service Bulletin (TSB) for this issue, but no recall. This is a serious safety concern because loss of power or stalling could cause an accident, especially at highway speeds or during turns/intersections. The repair is extremely costly for owners, and the defect appears to be widespread in 2018-?"2019 Accord models with the 1.5L turbo engine. This should be investigated and addressed as a recall to protect drivers.

On May 13, 2025, I took my car to the Honda dealership, because all of the lights on the dashboard came on. I was told that the clips on my turbocharger needed to be replaced, and so Honda fixed that $120 (diagnostic fee) $209.99 to fix the issue. I was traveling so they kept the car for a week. I received the car back, and about 2 weeks later, 06/03, the same thing occurred, I was told that the engine air filter needed to be changed, and it caused the lights to go off $32.84. The next day 06/06, the lights went off again. I took my car back to the Honda dealership and they had the car from 06/09 - 09/04. Today they have reached out to say -??It took a while to recreate the issue because they are -??masking each other.-?? There is a leak in the head gasket, and the turbocharger is going out.-?? It would be cheaper to buy a used engine and used turbocharger than to have it rebuilt.-?? I have spoken with other Honda owners, who have a 2018-2022 Honda accord, that have experience the same issue.

At 98,000 miles, the head gasket is blown. From a safety concern, the car goes into LIMP mode while driving and had to swerve out of traffic. A Honda Certified Dealer Service center confirmed the Blown head gasket It was only inspected by Honda Mechanics. The threw a service engine soon warning lamp which disabled the engine. This happened a few times while driving before getting it diagnosed.

2019 Honda Accord 1.5L turbo has confirmed cracked head gasket at 94,000 miles verified by certified mechanic. No prior warning light indicator. Car began misfiring and jerking while driving and was unable to accelerate. Took several weeks before the dash displayed any warning light indicator. After doing research, we were made aware there is a class action lawsuit against Honda Motor Company for this being a known issue in 2018-2022 Accords and it was never disclosed or addressed properly by Honda. This is a major safety concern as the car can shut off while driving, jerk, shake and lack acceleration.

My car has been sending several warnings including: Brake System: Electric Parking Brake System Problem, Brake System Problem, Brake Hold System Problem, Adaptive Cruise Control System Problem, Collision Mitigation Braking System Problem, Road Departure Mitigation System Problem, Supplemental Restraint System Problem, and Power Steering Reduction Problem. My car is not even 100,000 miles yet. I have had all maintenance done on time and recently had brakes replaced. I have changed my battery and tires twice within the 6 years of owning the car. It seems this is a regular complaint for such low mileage. I was a Toyota person but switched to Honda for their safety performance, and now I am regretting that. I read that this is the Turbo needing to be changed. This part should be recalled if it is failing soon. A person who just bought a car should not be paying $4500 in repairs already. I had the Fuel Pump recall replacement done, and had the brakes done. I am changing the spark plugs and ignition coils next week. Honda needs to do something about this and I am looking to join in the class action suit against them, if they do not correct the issue.

While driving ~40 mph call all of a sudden lost power in middle of busy street, was not able to steer or drive (pedals weren't working to provide power). I pulled off to side and saw check engine light blinking and warning message pop up about Brake system not working. I turned the car off then turned it back on and worked normally and was able to drive home.

Took my accord into service due to engine light warning, vibration on start up and to get the recall fixed. Was informed that my head gasket was misfiring and needed to be replaced, and was quoted $4515.37. The vehicle had been well maintained and low mileage at 72,000. This seems to be an issue with the 1.5 Turbo from 2018 to 2022 based on the online research. I decided to trade my vehicle in for a new one, but received $3500 less on trade in due to the bad head gasket. I'm also concerned about the safety hazard this could potentially have been. My daughter has a 2020 accord.

The vehicle displayed engine warning message -??Emission System Problem-?? at 70,000 miles and this appears to be present in many vehicles of this edition.

Lights go crazy in dashboard apparently due to constan cylinder misfires, spark plugs changed, same issue, fuel injectors and coils changed, same happened keep it getting fix and the problem persist, making the car dangerous to drive, since it loses power since the car it-??s not able to respond and work as it should be Having engine, steering and brake issues, problem has been confirmed by dealer. It hasn-??t been inspected by manufacturer. The lost of power and acceleration it-??s probably one of the symptoms before all the light go on again. It-??s been several times that this happens and I know for a fact that many people are experiencing this issues due to turbo or head gasket failure. Might get that inspected soon.

Head gasket issues and car overheated

NHTSA Vehicle Safety Complaint Vehicle: 2019 Honda Accord 1.5T Engine: 1.5-liter Turbocharged (L15B7) Mileage at Failure: 88,000 miles Issue: Blown Head Gasket / Coolant Leak / Engine Stalling Summary of the Problem: At approximately 88,000 miles, my 2019 Honda Accord 1.5T began exhibiting signs of a coolant leak and engine performance issues. After diagnosis by a certified mechanic, it was confirmed that the head gasket had failed, causing coolant to leak into the engine. This led to overheating and a dangerous engine stall while I was in active traffic, posing a serious safety risk. Safety Concern: The vehicle stalled unexpectedly in traffic due to the head gasket failure, putting me and surrounding drivers at risk of a crash. A blown head gasket can cause sudden overheating, misfires, and loss of power, all of which jeopardize the safe operation of the vehicle. This occurred without any warning lights or prior symptoms, making it even more dangerous. Repair Cost: The repair for the blown head gasket and associated engine work cost me $3,800 out of pocket, despite the vehicle being well maintained and relatively low mileage for this type of failure. Maintenance & Vehicle History: The car was serviced regularly according to Honda-??s recommended schedule. There were no prior signs of overheating or misuse. The stall happened suddenly, requiring the vehicle to be pushed to safety to avoid blocking traffic. Wider Problem Indication: This issue appears to be widespread among 2019-?"2021 Honda Accords with the 1.5T engine. Many owners report similar head gasket failures, indicating a potential defect in the engine-??s design, materials, or thermal management. Requested Action: I respectfully request that the NHTSA investigate this issue as a safety-related defect, and that Honda be required to issue a recall, extended warranty, or reimbursement program to address these premature and dangerous failures.

In December 2024, all of the lights on my dashboard came on & my car would not accelerate. The code indicated that it was a "Cylinder 2 Misfire." I replaced the ignition coil for cylinder 2 but my car continued to have the same issues. I had all 4 ignition coils replaced and all 4 spark plugs. In March 2025, all of the lights on the dashboard came on again with the car not accelerating properly. I had it looked at again, was told that it was a "Cylinder 2 Misfire" again but all 4 ignition coils were working properly. A spark plug was replaced at that time. Then, in May 2025, the car did the same thing with all of the lights coming and the car would not properly accelerate. The car again read that there was a misfire with "Cylinder 3" but all of the ignition coils worked properly. I had the fuel injectors replaced and another spark plug replaced. The car didn't even make it 24 hours before all the lights came on again. The RPMs in the car now go past "3" but will not accelerate & shift gears. The Honda Dealership has advised me that the head gasket needs replaced. My car has 74,000 miles on it. I had it inspected April 2024 with no head gasket issues & the car was at 64,000 miles approximately. So, in 8 months' time, the head gasket was blown & the car is well under 100,000 miles. I have been told that the engine my car has, 1.5L turbo with Honda has had this issue to the extreme that a class action lawsuit has been filed as Honda refuses to do any time of recall or assist with repairs. I literally had to drive with my 4 ways on to avoid being hit in an intersection due to the inability of my car to accelerate. The NHTSA needs to investigate Honda & determine if they are defrauding consumers by refusing to issue a recall due to this common & dangerous issue. I have owned 7 hours in the 30 years I have had a driver's license & never once had a head gasket issue or any issues to this extreme. I have never replaced a head gasket in any car that I have owned.
